Damage = Delete Chunk

Chunk Deleter" is a Minecraft Bedrock Add-on made of a Behavior Pack and a companion Resource Pack. Every time a player takes any kind of damage — from a mob attack, fall damage, fire, drowning, or anything else — an animated particle border instantly appears around the 16×16 chunk they're standing in, cycling between red and blue every half-second for a full 5 seconds. Once the countdown ends, the entire chunk (every Y level) is deleted and turned into air. The one exception is the Spawn Chunk, which is never deleted — instead, the player sees the message "This is (Spawn-Chunk)".
